【摘要】：近年来,流域经济快速发展,经济规模和经济发展速度不断提升的同时,流域生态环境遭到了严重破坏。经济发展模式的不合理性以及在经济发展过程中忽视经济与生态建设之间的协调关系,成为影响流域实现可持续发展的重要因素。渭河是陕西的“母亲河”,自西向东流经了宝鸡、咸阳、西安和渭南四市,全省的63%的人口住在渭河流域,渭河流域的经济发展和生态建设均在很大程度上影响着陕西人民的生活水平和生活质量。为此,测度陕西渭河流域经济与生态建设协调度,对认识和改善陕西渭河流域经济与生态建设的协调发展具有重要的理论意义和实践意义。论文主要研究陕西渭河流域经济与生态建设之间的协调度。首先对论文所涉及的相关概念及理论基础进行具体描述,并对国内外的相关文献进行了梳理,为本文的研究奠定了理论基础。其次,分析了陕西渭河流域经济与生态建设发展现状并对二者之间的对立统一关系进行了分析。再次,论文构建了流域经济指标体系和生态建设指标体系,并介绍了陕西渭河流域经济与生态建设之间的协调度由①流域经济系统内部协调度②生态建设系统内部协调度③流域经济与生态建设两个系统之间的协调度三个部分组成,其中流域经济子系统和生态建设子系统内部协调度运用序参量功效函数协调度模型计算,流域经济系统与生态建设系统之间的协调度运用主成分分析法、回归拟合模型以及模糊隶属度协调模型综合方法计算,最终得出陕西省渭河流域四市经济与生态建设之间的协调度,将四市流域经济与生态建设之间协调度运用算数平均法计算得到陕西渭河流域经济与生态建设之间的协调度。结果表明:(1) 2005-2014年陕西渭河流域经济与生态建设复合系统协调度虽然不断波动,但是整体呈现不断提升的状态,两系统也在朝着不断协调的方向发展。(2)陕西省渭河流域经济与生态建设发展协调度总体上分为三个阶段,2005-2008年的“不协调”阶段,2009-2011年的“弱协调”阶段,2012-2014年的“比较协调”阶段。(3)运用灰色相对关联法分析出影响协调度的五大主要因素分别为环境保护支出、经济发展水平、城市维护建设资金支出、废弃物的综合利用水平和社会固定资产投资。最后,根据以上结论提出了陕西渭河流域经济与生态建设协调发展的政策建议:促进流域经济结构调整;优化流域经济增长方式;提高流域生态建设水平;增强流域系统综合发展能力。
[Abstract]:In recent years, with the rapid development of the basin economy, the economic scale and the economic development speed have been continuously improved, at the same time, the ecological environment of the basin has been seriously damaged.The irrationality of the economic development model and the neglect of the harmonious relationship between economy and ecological construction in the course of economic development are the important factors affecting the sustainable development of the river basin.The Weihe River is the "mother river" in Shaanxi Province. It flows from west to east through four cities, Baoji, Xianyang, Xi'an and Weinan. 63 percent of the province's population lives in the Weihe River Basin.The economic development and ecological construction of Weihe River Basin affect the living standard and quality of life of Shaanxi people to a great extent.Therefore, it is of great theoretical and practical significance to measure the degree of coordination between economy and ecological construction of Weihe River Basin in Shaanxi Province, to understand and improve the coordinated development of economy and ecological construction of Weihe River Basin in Shaanxi Province.This paper mainly studies the degree of coordination between economy and ecological construction of Weihe River basin in Shaanxi province.First of all, the related concepts and theoretical basis of the paper are described in detail, and the relevant literature at home and abroad are combed, which lays a theoretical foundation for the research of this paper.Secondly, the present situation of economic and ecological construction in Weihe River Basin of Shaanxi Province is analyzed and the unity of opposites between them is analyzed.Thirdly, the paper constructs the watershed economic index system and the ecological construction index system.The coordination degree between the economy and ecological construction of Weihe River basin in Shaanxi province is introduced, which is composed of three parts: the internal coordination degree of one basin economic system, the internal coordination degree of ecological construction system and the coordination degree between the two systems of basin economy and ecological construction.The coordination degree of watershed economic subsystem and ecological construction subsystem is calculated by order parameter efficiency function coordination model, and the coordination degree between watershed economic system and ecological construction system is calculated by principal component analysis.Regression fitting model and fuzzy membership coordination model are used to calculate the coordination degree between economy and ecological construction of four cities in Weihe River Basin of Shaanxi Province.The degree of coordination between the economy and ecological construction of the four cities is calculated by using the arithmetic average method and the coordination degree between the economy and ecological construction of the Weihe River basin in Shaanxi Province is obtained.The results show that the coordination degree of the complex system of economic and ecological construction in the Weihe River basin of Shaanxi Province from 2005 to 2014 fluctuates continuously, but the whole system presents an increasing state.The coordination degree of economic and ecological construction of Weihe River basin in Shaanxi Province is divided into three stages: "uncoordinated" stage from 2005-2008 to "weak coordination" stage from 2009-2011 to 2012-2014.The grey relative correlation method is used to analyze the five main factors that affect the degree of coordination, which are the expenditure on environmental protection.Level of economic development, expenditure of urban maintenance and construction funds, comprehensive utilization of waste and investment in social fixed assets.Finally, based on the above conclusions, the author puts forward some policy suggestions for the coordinated development of economy and ecological construction in Weihe River Basin of Shaanxi Province: to promote the adjustment of basin economic structure, to optimize the mode of economic growth in the basin, to improve the level of ecological construction in the basin;Strengthen the comprehensive development capacity of watershed system.
